good idea, maybe when we need more things you can be a brainstormer along with zoroarkcity.Love your idea :3
Could you add some early way to obtain the slime staff, or another early summon?
It's a pain in the to get the Slime Staff, and you could add a "goldenfish" summor or something, that could be the first angler quest reward. Like, 7 damage and works well on water, but slow in earth (except when it's raining).
